Well, it seems we are once again a floating point of awareness in Fallout 4 whilst in first-person view. Unless I missed something, all the body shots were from a (sometimes close, in dialog) external camera. I didn't notice any visible body from the first-person shots, and while the main character was walking through the house right after chargen, the walking seemed totally smooth. Plus, when the dog(meat) handed the wrench to the character at the gas station after retrieving it, the wrench simply disappeared into inventory from his mouth (no reaching hand, in other words).
This rather disappoints me, I have to admit. I never play without an Enhanced Camera mod for a visible me any more, don't know about you guys, but I think that's an evolutionary leap in the game's realism.
*Please* correct me if I'm wrong. :)
